Optical cable with core decoupled from sheath and yarn strands uniformly adhering to sheath

摘要

An optical fiber cable including at least one module with at least two optical fibers enveloped by a plastic covering, a plastic sheath around the module, and tensile-resistant fibrous yarn strands arranged between the module and the plastic sheath. The sheath and the module are decoupled during manufacture by separate pulls on the module and yarn strands. The yarn strands are caused to adhere uniformly to the sheath, so that any stress to which the sheath is subjected in service is distributed uniformly within the core. The uniform adherence is preferably caused by one or more flexing actions performed on the cable during manufacture.
